Antibiotic Resistance Genes Accumulating in Lake Geneva Via Wastewater Treatment Plants

Via ScienceDaily:

Large quantities of antibiotic-resistant bacteria enter the environment via municipal — and especially hospital — wastewater streams. Although wastewater treatment plants reduce the total number of bacteria, the most hazardous — multiresistant — strains appear to withstand or even to be promoted by treatment processes. This was demonstrated by Eawag researchers in a study carried out in Lake Geneva, near Lausanne.

Treated wastewater from the city of Lausanne — around 90,000 m3 per day — is released into Vidy Bay (Lake Geneva); the discharge point is located 700 m offshore, at a depth of 30 m. The Lausanne region does not have a pharmaceutical industry or intensive animal production. However, the Lausanne treatment plant receives wastewater not only from the region’s 214,000 inhabitants and a number of smaller healthcare centres, but also from a major healthcare facility — the University Hospital of Canton Vaud (CHUV).

As studies from the hospital and veterinary medicine sectors have indicated an increasing prevalence of antibiotic resistance, a group of researchers have now investigated whether resistance genes also enter the environment — specifically, Lake Geneva — via wastewater treatment plants. Resistance testing was performed using both traditional culture methods and elaborate genetic analysis …

  1. just dump it in the lakes! man! who the crap comes up with these ideas!
    fakkin disgusting!
